GENETIC-CONTROL OF SYNTHESIS OF ENZYMES O F THE COMMON SITE FOR THE AROMATIC PATHWAY IN PSEUDOMONAS BACTERIA

We have shown recently that the first stage of the common site for the aromatic pathway in Pseudomonas aeruginosa, P. putida, P. fluorescens , P. acidovorans, and P. testosteroni is controlled by repression of - deoxy-D-arabinoheptulosenate-7-phosphate-synthase synthesis with pheny lalanine and tyrosine. This work is devoted to the study of genetic co ntrol of the remaining six stages of the common site for aromatic path way in representatives of Pseudomonas genus using auxotrophic and regu latory mutants it was shown that genes aroB, aroD, aroE, aroL, aroA, a nd aroC operate constitutively in P. putida, P. mendocina, P. marginat a, and P. acidovorans.
